Copa Airlines flight 135, a Boeing 737-800, veered off the left side of runway 03R while landing at Panama City-Tocumen International Airport.
Before starting the approach the crew carried out a Forward threat briefing, highlighting that the reverser of engine no.2 was inoperative per MEL. In case the runway was wet and in case of an asymmetry they would not use the engine no.1 reverse.
At the moment of touchdown the crew felt a vibration as if a wheel was deflated, with a strong yaw to the left. They proceeded to apply full rudder to the right to direct the aircraft towards the runway centreline and activated the reverse of engine no.1 to slow the aircraft without success. Perceiving that the yaw moment was increasing and following the procedures, the pilot kept the reverse and continued applying full deflection on the right pedal to return the aircraft to the runway centreline without success.
The aircraft went off the side of the runway and stopped. The crew analyzed the situation perceiving a strong smell of burning. The nose gear was collapsed and to avoid possible further damage they decided to shut down the engines, and verified that there was no indication of OVERHEAT or FIRE, proceeded to start the APU to have an alternate power source. An evacuation was carried out without incidents or reports of any person with any injury.
